When I'm using my 706mkiig remoterig setup on HF, on 80M (that's the only band I've noticed so far), when I'm transmitting, I see random characters come up on the 706 screen and sometimes the screen even flashes. Any idea what is causing this? Is it RF getting into the cable between the 706 radio and remoterig box? If so, can I wrap a ferrite core around it to help? Any other thoughts/suggestions?
Thanks!
